Application filed October 13, 1924.. Serial no. 743,414.

To all whom u may concern: Be it-known that I, JAMES E. Jnnnms, a citizen of the United 'States, residing at Highland Park, in the county of'Wayne and State of Michigan, have invented new and useful I'mprovementsin Motor- Vehicles, of which the following is a specification. -My present invention has referenceito motor truck construction. '10

the body thereof will be more effectively sup iprted than is the body of an ordinary true v A further object is the construction of a truckoframe wherein the steering wheels are mounted to the rear of the motor and whereby the truck can make a shorter turn than that'oftheordinary construction.-

p The invention further resides in the cons struction, combination and operative asso-.

ciationof parts .suchfas is disclosed by the udrawings which accompany and'which form part of'this application. r

In the drawings v Figure 1 is a jside elevation ofthe improvement with parts in section.

' Figure 2 is a sectional view approximately on the line 2-2 of Figure 1. a Figure 3 is a top plan view of theimprovement.

- Figure 4" is a fragmentary sectional view approximately on the line 4-4 of Figure 2. My truck frame construction includes the usual channeled side members or sills 1 con nected together at desired intervals and having their rear ends downwardl arched. To

the arched ends of the sills t ere are connected one ,end of semi-elliptical springs 2 on which the rear axle-3 is supported. The inner ends-of the springs 2 areconnected to suitable shackles 4-which depend from the 1 sills 1. The rear axle .is straight and is not provided with the usual differential housing. Mounted on the spindles of the axle 3 directed hubs 5 for the drivefwheels-b. T e hubs carry onth'eir.

inner ends sprockets around which are trained endlessrhains 7, the said chains being also trained around smaller s rockets 8 journaled on a shaft 9'mounted1n bear-- ings 10 on the sillsat a suitable distance inward with respect to the forward endof An object is to construct atruck-whereby the frame. The shaft 9 isrevolved by intermeshin'g gears or similar means operated by the motor 11 of the improvement. The mo tor is suitably supported and the'radiator 12 therefor is mountedon'the front of the frame.

are semi-elliptical springs 13 that support the front axle l4. I r 1 By reference to the drawings it will be noted that the front axle 14 is mounted be-' low the shaft 9, and consequently at a suitable distance from the front end of the -which is pivoted a bar 19. The bar has its I rear end upwardly inclined and from thence straight, the said straightened portion being provided with an elongated. slot 20 through which passes a guide pin 21 arranged on one of the cross beams 22 that connects the sills Suitablyconnected by shackles or a the'like to the under face of the sills 1 there to the frame.v The bar 19 serves as a sta- 1" .bilizing element for theaxle 14. i

,On its rear face, the axle'jl 4, at equidistance from the cars 18, is provided with offset s herical heads 23 over which are otally' connected a link 26. The links 26 1 also terminate in ball heads which are engaged by cup members 27 formed. on the endsof angle arms 2 8 which are upwardly extended andwhich terminate in a socket member 29 in which the steering post 30 is secured. The steering postis provided with the usual steering wheel 31.

- The improvement provides a direct drive and dispenses with a great number of parts usually employed-' in truck constructions. Control means are provided for the engine,

but as the same may be of any class, their.

illustration is not deemed necessary.

Having described the invention, I claim A motor truck construction in'which the led axles for the drive and for the steering I wheels are supported from semi-elliptical springs connected to the sills of the truck frame and in which therear wheels are chain driven by the engine, a plate supported by the frontsprings and to which the front axle is pivoted, arms having a ball and socket connection with the front axle,

links nivoted to the arms, an angle member having a. ball and socket connection with the 14) b5 2) JAMES E. JENKINS
